Yes, like Elvis Presley and Michael Jackson, the hognose snake knows when it's opportune to fake being dead. In the animal kingdom, it's typically done because certain predators will avoid carrion, but lots of mammals and birds of prey have no such qualms about dead snakes. It's just that the hognose snake attacks the role with such vigor that no one has the heart to tell it the truth.
It will convulse wildly, flip over on to its back and lie nearly motionless even when prodded. The hognose death-stagger is so overwrought that even Jim Carrey's directorial notes advise dialing it back.
In some cases it accompanies the performance with a lolling tongue and--get this-- will even spew blood from its mouth and anal openings.
It is so dedicated to the role that if reset on to its stomach, it will immediately flip over to its back. What it lacks in an understanding of death it certainly makes up for in commitment.
Even weirder, when finally forced to fight, the hognose snake will imitate a cobra. It'll flatten out the skin on its neck, and even coil and strike (remember, its lack of fangs make striking useless--it's all for show).
We say it's weird because they don't live on the same continent as cobras, aren't directly related to them and there's no fossil evidence that they ever crossed paths. It's imitating behavior it's never seen in person, so we have to assume they just saw a cobra on TV at some point.
